Environment is ready.
My goal has been reached. I learned how to make modular environments from scratch, how to configure lights and reflections, how to optimize level, how to use sequencer and a lot more.
I think I made a good basis for the near-future environment, which can be extended by additional props to suit different needs of different types of games.
I will try to publish this environment to UE marketplace. But because I used 4.14 for making it, I have to wait for the new UE4 release and after that around 1 month to complete submission process.
And now it’s time to find a new project…
